Wanting to quit breastfeeding

I just simply emotionally cant do it anymore. The mastitis in both my breasts, the constant clogged ducts, the pain, the now infected right breast. I dont want to be tied to a pump (not to mention the one I bought sucks and cant afford another one), i dont have time to keep doing compresses all that stuff I have literally tried everything and these clogs wont go away. She has a lip tie and no one around my area will remove it, paired with an extremely strong suck. I have a very busy busy schedule. Im a stay at home mom but im in my graduate classes for college and am so behind with having 4 classes to get done with only 2 months left which ive only read 2 chapters for one my classes in this whole month. I dread putting her on my breast every single time. Im getting my gallbladder taken out next week so im going to be stressed after it gets taken out. Shes only a month old and I wanted to make it to 6 months but Im so emotionally stressed. I just want to be able to lay her on my chest to cuddle without pain because of the hard tender lumps. I want to be able to sleep in bed without being in pain. How do I dry up my milk? How do I stop breastfeeding without feeling tortured? I felt so relieved when my husband gave her a bottle only because I didnt have to put her on my boob and go through that pain.
